Ewing was linked to the crimes in July through a DNA match. He is suspected of breaking into metro area homes and bludgeoning three members of an Aurora family and a Lakewood woman to death with hammers.

Ewing appeared at 3:30 p.m. before Judge James Wilson in a Carson City courtroom for the extradition hearing.

Ewing, who has been incarcerated at Northern Nevada Correctional Center in Carson City since 1985 on a 40-year attempted murder conviction, has been fighting extradition to avoid two Colorado trials for sexual assault, robbery and murder charges.
